I played the prologue version which is free. It's really cool concept and I enjoyed playing it. However prologue was more than enough, I don't think I would finish the full game. I found myself often lost and not being sure what to do, and that brought quite some frustration up. It's a quite unique game, I recommend trying the prologue and if that's something you enjoy go ahead and finish the whole game, but like I already said for me prologue has been enough.
